Abstract
The objective is to test the modelling approaches and the reliability of the codes
used in water risk assessment. The final goal is to elaborate, for each group of
pollutant, guidelines that could serve as a scientific support for pollutant
transport modelling in groundwater and soil.
The models performed by 5 teams to simulate a contamination of soils and
groundwaters by PAH at a disused coke plant site were compared. Hydrogeology
is characterised by a superficial and a chalk aquifer, the latter being confined
under a 2 meter thick clay layer. The source of contamination was determined by
40 soil sampling points. Total PAH concentrations in the soils ranged from 3 to
80000 mg/kg.
